Pos station output signal conversion method and system

Abstract

A method for processing single line data and multiple line data generated at a POS station for driving a printer thereof into common structure data, e.g., single line data, the method comprising the steps of defining a first lookup table having first signal content corresponding to literal article identifications of articles and article price encompassed in the single line data and having second signal content corresponding to literal identifications of articles encompassed in the multiple line data and flag data, defining a second lookup table having signal content corresponding to article identifications of articles encompassed in the multiple line data cross-correlated with additional multiple line data, furnishing the single line data and multiple line data generated at the POS station for driving the printer thereof to the first lookup table and determining correspondence of literal identifications in the single line data and the multiple line data with literal identifications stored in the first lookup table and detecting flag data therein. Upon determinations of correspondence of literal identifications without accompanying detection of flag data, the contents of the first lookup table are furnished as single line output data. Upon determinations of correspondence of literal identifications with accompanying detection of flag data, the contents of the second lookup table are furnished as single line output data. A system for implementing the method includes circuit means for performing the foregoing steps of the method.
